J.J. McCarthy enters Year 2 with the full weight of Minnesota’s offense on his shoulders—and all the tools to deliver in a big way. The 10th overall pick in the 2024 NFL Draft, McCarthy now inherits the QB1 role in Kevin O’Connell’s system after a redshirt rookie season following a preseason meniscus tear. In limited action, McCarthy flashed elite traits—mobility, velocity, and sharp middle-field processing—and now steps into an ecosystem that’s made stars out of far lesser talents.

Why J.J. McCarthy Could Be a League Winner in 2025

The Vikings have quietly become one of the most quarterback-friendly systems in fantasy football. From Kirk Cousins to Sam Darnold to even Nick Mullens, every signal-caller under Kevin O’Connell has exceeded expectations. In 2024, Darnold finished as QB11 in points per game. The year before? Joshua Dobbs ranked QB10 during his stretch of starts. That same structure now supports a more talented passer with a higher ceiling.

And what a supporting cast: Justin Jefferson, Jordan Addison, T.J. Hockenson, Aaron Jones, and one of the NFL’s most improved interior offensive lines. McCarthy also brings sneaky rushing value—he posted a 4.48 40 at Michigan and rushed for nearly 300 yards in his final college season. He’s a natural fit in O’Connell’s intermediate-heavy passing attack and thrives attacking the middle of the field, where Minnesota builds its rhythm.

McCarthy has already shown he can deliver under pressure. In Michigan’s national championship run, he posted a 72.3% completion rate, elite efficiency in scramble drills, and showcased an NFL-caliber arm. Now, with full control of the Vikings offense, he’s positioned to be this year’s best value at quarterback.

J.J. McCarthy 2025 Dynasty Superflex Fantasy Outlook

J.J. McCarthy currently ranks 55th overall and QB17 in Superflex dynasty ADP. That’s behind several veterans with lower ceilings and less job security. But fantasy managers should take note: McCarthy projects for over 4,200 passing yards, 28 touchdowns, and nearly 300 rushing yards in Year 2. Those numbers would push him into the QB12–QB8 range in most formats.

If you’re punting QB early in dynasty startups or seeking long-term value in redraft, McCarthy is a perfect blend of floor and ceiling. The weapons, the system, and the draft pedigree are all there. He’s not just a breakout candidate—he’s a potential league winner in 2025.
